With over 30 years' experience in environmental assessments, remediation and management, Reidar has directed and managed many large contaminated soil, groundwater and sediment projects from the initial investigations to implementation of remediation and/or risk management solutions. He provides specialist review and advice on brownfield remediation and redevelopment projects in Canada and abroad. In his role as past Chair of the Contaminated Sites Roster of Professional Experts, Reidar has been leading the development of the new and expanded contaminated sites approved professional review system, designed to assist the Ministry of Environment with issuance of regulatory instruments. With a desire to see the development of a true community of contaminated sites professionals, Reidar opened GeoEnviroLogic Professional Development to bring practitioners, regulators and others together to share information and learn from one another's experiences. Reidar also teaches part-time in UBC's departments of Civil Engineering and Earth Sciences as Adjunct Professor.
